OERA Open Source Initiative

Fri, 2008-08-29 21:55 — tamhas

The OERA Open Source Initiative (OERA OSI) is a project to define, create, and refine a series of production quality components which can serve as a sound basis for those creating their own OERA implementations. The primary focus will be components which would form a portion of the Common Infrastructure portion of the standard OERA model, but we will not exclude contributions for other sorts of helper classes which might be used as part of a Data Access, Business Logic, or UI layer.


Exception and Condition Handling Classes

Wed, 2006-10-04 19:31 — tamhas

One of the problems faced by ABL programmers for many years is the lack of a true exception handling mechanism in the language. By “exception handling”, we mean a mechanism by which a program encounters an error or unexpected condition then can communicate up the call stack with the purpose of:
1. Signaling that requested execution has not completed as expected;
2. Communicating any necessary information about the details of why this condition occurred; and
3. Providing a structure such that the condition is “handled” in a graceful fashion at an appropriate level in the code.


Collection and Map Classes for OOABL

Wed, 2006-10-04 19:23 — tamhas

In developing a foundation framework for Object-Oriented ABL, it seems natural to consider creating a set of Collection classes since they have a broad utility in OO design in other languages. It also seems natural to consider imitating the Collection classes in Java since that is a tried and true implementation into which there has been a considerable investment of thought and effort.


Advanced Business Logic Sample Code

Fri, 2006-06-23 16:27 — rssreader

This sample code complements Implementing the OpenEdge® Reference Architecture: 7: Advanced Business Logic. Seventh in a series by Progress Fellow John Sadd on applying the OpenEdge Reference Architecture principles to building applications, this white paper and accompanying code samples discuss in depth best practices regarding database trigger procedures, transaction scoping, referencing between business entities, and extending exception handling.


Context Management Sample Code

Thu, 2006-06-22 12:32 — rssreader

This sample code complements Implementing the OpenEdge® Reference Architecture: 8: Context Management. Eighth in John Sadds series on the OpenEdge Reference Architecture, this paper is aimed at complex WebSpeed applications and describes how to implement a context management service for using ProDataSets in large database transactions consisting of several changes.
